I can’t comment on the use of “Uncle Tom” specifically.
But we ought not to use insults like that ever. By using them on people who “deserve it”, we are basically saying these terrible things are true, but we usually don’t say them because it’s rude. A better way to think is that we don’t use discriminatory insults/slurs because the hatred they represent is completely without merit.
